Gene therapy: a promising candidate for cystic fibrosis treatment
An improved gene therapy treatment can cure mice with cystic fibrosis (CF). Cell cultures from CF patients, too, respond well to the treatment. Those are the encouraging results of a study presented by the Laboratory for Molecular
Pollen and vegetative microspores as sensitive systems for ozone
The high ground-level ozone concentrations (higher than 0.1 μl/l per hour, in which there is a characteristic odor) is an biggest danger for human health. In environmental biomonitoring of O3 hazardous concentrations in air or chronic levels
Endocrine regulation of Alzheimer’s disease. The Achilles heel of dementia and other neurological conditions
Alzheimer’s disease (AD) is the most common disorder of the central nervous system and the most frequent cause of devastating dementia in the elderly. Typified by loss of memory and by cognitive decline, AD lowers the quality
Extracorporeal life support in polytraumatized patients
Major trauma is a leading cause of death, in particular amongst young patients, causing more than 5 million victims every year worldwide. Early causes of death (usually related to severe hemorrhage, pulmonary failure, cardiovascular shock or extensive
Small fish can help finding antimalarial drugs with less severe side effects
In 2012, over 200 million cases of malaria have been reported. Vaccines for malaria are under development; however, no generally accepted vaccine that also works for adults is yet available. Therefore, drugs will in the foreseeable future
Ultrasensitive detection of influenza viruses by glycan biosensors
These days there is a considerable interest to develop devices, which are able to detect various diseases at early-stage with a high speed and reliability to enhance efficiency of subsequent disease treatment. The first step towards this goal
Relationship quality and sleep
The quality of social relationships and social support appears to be associated with physical health outcomes and sleep quality. Almost all previous research in this area focuses on positive aspects of relationships. In addition to supportive relationships,
Diagnosis of small cell lung carcinoma metastases
Cancer is defined by unscheduled cellular growth and metastatic spread into other organs of the body. Tumor cells gain their capacities form genetic alterations, also known as mutations, leading to altered protein functions and signaling pathways. Tumors
Improved antibody selection with assisting plasmid
When the human body is invaded by foreign molecules, the immune system will be activated to fight against these intruders. This is done with the help of antibodies which act as the defence force of our body.
Origin of photosynthesis: Is photosynthetic ability present in Actinobacteria?
The origin of photosynthesis, which sustains most life on earth, by converting light energy from the sun into chemical energy for plants, animals and other organism, remains an important unresolved problem in the history of life. Besides
Unusual behavior of benzoic acid at low temperature
Molecules of benzoic acid form dimers in the crystal, which is doubly hydrogen bonded through the carboxylic COOH groups (Fig. 1.). Since the left and right site of the dimer are fully equivalent, the protons “do not
Valproic acid treatment for brain tumors
Tumors arising in the brain represent only 2% of all cancers diagnosed in the United States with 23,000 new cases and 14,000 deaths annually. The World Health Organisation (WHO) classifies brain tumors from grade 1 to grade
Markers that predict treatment response to inhaled corticosteroids in children with asthma
Asthma is a common chronic condition caused by inflammation in the tubes that pass air in and out of the lungs. When asthma is poorly controlled, children cannot breathe normally, cannot play and exercise, and may have
A brucellosis vaccine that provides sterile immunity
Brucellosis is a disease caused by infection with bacteria of the genus Brucella. Most of Brucella species are capable of infecting humans, and they are all considered zoonotic since different animals are their preferential hosts. Brucella ovis
Non-genetic health professionals’ perceptions of genetic testing for hereditary cancer
Over the last decade more genetic tests are being ordered by non-genetic health professionals, such as oncologists, gynecologists, and primary care providers. Numerous studies have shown that non-genetic health professionals have insufficient knowledge of genetics, express educational
Chemically exfoliated MoS2 on TiO2 mesocrystal with efficient photocatalytic hydrogen evolution
Over the past decades, the rapid depletion of fossil fuels and serious environmental pollution were started to strongly affect the modern society. With concerning the deficiency of human energy and alleviating the environmental pollution, solar energy as
Could a newly-discovered bacteria contribute to cancer?
For many years, doctors and scientists have known that certain viruses, such as human papilloma virus (HPV), are capable of causing cancer. Until recently, bacteria were ignored as potential carcinogens. This changed with the discovery that Helicobacter
The fate and influence of engineered nanoparticles in wastewater treatment plants
Engineered nanoparticles (ENPs) (intentionally created particles with one or more dimensions greater than 1 nanometer and less than 100 nanometers) are now used in consumer and industrial products. However, there are concerns surrounding their potential effects on
Why do obese individuals choose to be active?
Individuals with a body mass index (BMI) over 30 are labelled obese and urged to lose weight. This often includes encouraging physical activity, but most individuals who lose weight regain the weight they lost. Without weight loss,
